Nor-ursodeoxycholic acid in hepatobiliary diseases: A narrative review.
Review in World journal of gastrointestinal pharmacology and therapeutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Nor-ursodeoxycholic acid (nor-UDCA) is a side-chain shortened analogue of ursodeoxycholic acid (UDCA). Because of its biochemical modification, it is resistant to amidation. Nor-UDCA undergoes cholehepatic shunt, leading to increased bicarbonate secretion. In addition, it has shown potential antifibrotic activity in the animal model of cholestasis and fibrosis. Nor-UDCA has several advantages over UDCA in its pharmacokinetic and pharmacodynamic properties. However, its safety and efficacy data on cholestatic diseases are largely extrapolated from pre-clinical animal studies. Vitamin E, resmetirom, peroxisome proliferator-activated receptor agonists, and incretin-based therapies dominate the pharmacotherapeutic armamentarium for metabolic dysfunction-associated steatotic liver disease or steatohepatitis. Recently, nor-UDCA has been evaluated in patients with metabolic dysfunction-associated steatotic liver disease with conflicting therapeutic benefits and a controversial trial endpoint. This comprehensive narrative review focuses on its novel mechanism of action, comparison with UDCA, and underscores the limited evidence of its safety and efficacy in various hepatobiliary diseases. This review also discusses future research prospects of nor-UDCA in hepato-biliary diseases, which addresses the research gap in existing literature.
